Other terminations available at additional cost. Weight 2.4 g Ambient temperature -40C to +125C Storage temperature Component: -40C to +125C. Packaging: -40C to +80C Resistance to soldering heat Max three 40 second reflows at +260C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 85% relative humidity) Packaging 400 per 13 reel Plastic tape: 32 mm wide, 0.4 mm thick, 20 mm pocket spacing, 7.6 mm pocket depth Failures in Time (FIT) / Mean Time Between Failures (MTBF) 38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332 PCB washing Only pure water or alcohol recommended Part number1 DA2062-AL_ Inductance at 0 Adc2 10% (H) 120 Inductance Leakage at Ipk3 DCR max inductance4 min (H) (Ohms) max (H) 97 0.475 (pins 3 - 1) 3.0 0.013 (pins 9 - 6) 0.013 (pins 10 - 7) 0.181 (pins 4 - 5) Turns ratios5 pri : sec pri : bias 1 : 0.1 1 : 0.4 Ipk3 (A) 0.64 Secondary output 3.3 V, 2 A 1. When ordering, please specify a packaging code: DA2062-ALD Packaging: D = 13 machine ready reel. EIA-481 embossed plastic tape (400 per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance is for the primary, measured at 375 kHz, 0.6 Vrms, 0 Adc. 3. Peak primary current drawn at minimum input voltage. 4. Leakage inductance is for the primary and is measured with secondary windings shorted. 5. Turns ratio is with the secondary windings connected in parallel. 7. Output of the secondary is with the windings connected in parallel. Bias winding output is 14 V. 8. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
